CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Patent Application Ser. No. 62/766,213, having a filing date of Oct. 5, 2018, and entitled “Varieties of Z. aethiopica Calla Lily Plants”, the entire disclosure of which is incorporated herein by reference.

Botanical classification: Zantedeschia aethiopica.

Varietal denomination: ‘Diva Siberia’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of calla lily, botanically known as Zantedeschia aethiopica and hereinafter referred to by the cultivar name ‘Diva Siberia’.

‘Diva Siberia’ is a product of a planned breeding program and the new cultivar was selected in Santa Cruz, Calif. from the F2 population of the crossing of unpatented Zantedeschia seedling 7037-07 (female parent) with unpatented Zantedeschia seedling 95104 (male parent).

Asexual reproductions of ‘Diva Siberia’ have demonstrated that the combination of characteristics as herein disclosed for the new variety are retained and reproduced true to type through successive generations of asexual reproduction.

Color references are made to the 2001 R.H.S. Colour Chart of The Royal Horticultural Society of London, 4^(th) Edition, except where general color terms of ordinary significance are used.

The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

The following traits have been repeatedly observed and determined to be basic characteristics of ‘Diva Siberia’ which, in combination, distinguish this calla lily as a new and distinct cultivar:

-   -   1. White colored spathes; and     -   2. Leaf maculations absent.

Table 1 provides a comparison of ‘Diva Siberia’ to similar Zantedeschia aethiopica varieties ‘A405’ (U.S. plant patent pending), ‘Colombe de la Pair’ (unpatented), ‘Avalanche’ (unpatented), and ‘Innocence’ (unpatented). Further, ‘Diva Siberia’ flowers one week earlier than ‘Innocence’ and is more productive.
